The Helsinki tram network forms part of the Helsinki public transport system organised by Helsinki Regional Transport Authority and operated by Helsinki City Transport (Finnish: Helsingin kaupungin liikenne, Swedish: Helsingfors stads trafikverk) in the Finnish capital city of Helsinki. The trams are the main means of transport in the city centre. 56.7 million trips were made in 2013. The Helsinki system is one of the oldest electrified tram networks in the world.
In 2016, approximately 38 km (23.6 mi) of double track was in operation with 13 routes.
In addition to the 13 regular lines two special ones exist: the museum line operated by Helsinki City Transport in collaboration with Oy Stadin Ratikat Ab and the Spårakoff pub tram, both of which run during the summer months. These lines do not appear in the route map included with this article.
The tram network is built almost exclusively on the streets of Helsinki, making it a traditional tram system rather than a light rail one. The track gauge is one metre. The network consists almost entirely of double track. In some parts the tracks are separated from other road traffic; elsewhere they share road space with cars and buses.
The trams are powered with electricity conveyed by overhead wires. Trams have their own traffic lights, distinguished from normal lights in that they are based on symbols of single colour: an upward-pointing arrow signifies "go", a horizontal line "prepare to stop" and the letter S "stop". The traffic lights are synchronised to allow tram and bus traffic to flow relatively smoothly. This system is called HeLMi (Helsinki Public Transport Signal Priority and Passenger Information).
